BRIEF DESCRIPTION OF THE INVENTION The present invention relatesgenerally to improvements in swimming pools and, in particular, itrelates to an improved swimming pool which is assembled fromprefabricated panels and frame members.

The use of above-ground swimming pools constructed from prefabricatedparts is becoming increasingly popular. However, the problem ofproviding an above-ground pool which is easily assembled, strong anddurable, has continued to be a problem in industry. It is, therefore, aprimary object of the present invention to provide an improvedabove-ground pool which is easy to assembly, structurally sound, durableand designed in such a manner that no reinforcing rods or straps passacross the inside bottom of the pool. In addition, it is an object toprovide a swimming pool having an elevated deck extending entirelyaround the upper periphery of the pool, which has decorative side panelsto conceal the filter system and pumps of the pool, as well as the outersurfaces of the pool sidewalls. Roll-away steps are also utilized in thepool of the present invention which can be stored and locked in placeunder the deck when not in use so that small children cannot gain accessto the pool.

In accordance with the above objects, the rectangular swimming pool ofthe present invention comprises four walls which are joined together atright angles in such a manner as to assure maximum strength. The comersof the pool are provided with comer cove members to prevent waterstagnation and the walls are made up of a plurality of panels havingintegral channel or L shaped lower portions, which overlie a block orconcrete foundation. The channel or L shaped portions maintain the lowerportions of the walls in position when internal pressures are exerted onthe walls by water within the pool and also provide a safety ledgearound the perimeter of the pool. v

Extruded hanger elements, for anchoring the peripheral edges of the poolliner in place, extend around the inner edge of the pool deck and aresecured by bolts to the deck and outwardly extending flanges of the wallpanels. Coping elements are provided which both cover the hangerassembly and help retain the peripheral edge of the liner on theextruded hanger elements.

The elevated deck, which is provided with leveling jacks, extends aroundthe upper peripheral edges of the pool, is supported by a lower poolenclosure assembly and held down by adjustable torsion cables which areconnected to the deck structure so as to exert a downward and inwardforce on the deck. The torsion cables are anchored to the corners of theool at their ends and passing around the outer edges of deck framemembers intermediate their ends. The frame members extend along thejoints of adjoining deck panels or sections and are secured to thepanels so that the forces exerted on the frame members by the torsioncables are transmitted to th deck.

The lower pool enclosure assembly has struts which not only support theelevated deck, but also carry lower decorative panel assemblies thathide the outer surface of the pool sidewalls, the pump and the filterequipment utilized with the pool. Roll-away stairs are provided at oneend of the deck with the upper ends of the stairs being mounted ontracks which extend beneath the deck so that the stairs may be storedand locked in place under the deck when not in use.

DETAILED DESCRIPTION OF THE INVENTION Referring to FIGS. 1 through 4,the swimming pool is generally designated by reference character 20. Thepool comprises sidewalls 22, 24, end walls 26, 28, a level or concavesand floor 30 or a floor with a hopper 32 and an elevated deck 34 whichextends entirely around the tank of the pool.

The sidewalls 22, 24 and end walls 26, 28 of the pool are made up ofmetallic panels 36 or 36' which, as best illustrated in FIGS. 4, 5 and6, are mounted on a cinder block, cement or similar foundation. In thepreferred form of the invention, a trench about the depth and width of astandard cinder block is dug around what will be the inside perimeter ofthe pool side and end walls. When the trench has been leveled, a cinderblock or cement foundation 38 is placed therein and the wall panels 36of the pool can be put in place.

To anchor the wall panels 36, 36 to the cinder block or cementfoundation 38, the lower portion of each panel 36, 36' is provided withan inwardly extending, downwardly opening, channel or L shaped extension40 or 40 which overlies the cinder block or cement foundation.

As shown in FIG. 5, L shaped extension 40' comprises an intennediatehorizontal web 44' about the width of a cinder block and a vertical3-inch flange 46 extending downwardly from the inner end of web 44.Flange 46' engages the inner surface of foundation 38 while the lowerterminal portions of vertical channel members 48 engage the outersurface of foundation 38. With this arrangement, inner flange 46'maintains the lower portions of the panels, and consequently, the'sidewalls in a fixed position when the sidewalls are subjected tointernal pressure from water within the pool. In addition, the L shapedextension 40' along with the lower terminal portions of frame members 48provide means for properly aligning and positioning adjacent wall panels36 of the assembly. The panels 36'. of sidewalls 22, 24, and end walls26, 28 are bolted or otherwise secured to the webs of vertical channelframe members 48 which extend along'the joints formed by the abutting oroverlapping edges of the wall panels from the upper edges of the panelsto 3 inches below the juncture of terminal extensions'40' with the uppervertical portions of panels 36'.

As shown in FIG. 6, the channel-shaped extension 40 com prises an outervertical flange 42, an intermediate horizontal web 44 about the width ofa cinder block and an inner vertical 3-inch flange 46. The inner flange46, which engages the inner surface of foundation 38, maintains thelower portions of the panels, and consequently, the sidewalls in a fixedposition when the sidewalls are subjected to internal pressure fromwater within the pool. In addition, thechannel-shaped extension 49provides means for properly aligning and positioning adjacent panels ofthe assembly, The panels 36 of the sidewalls 22, 24, and end walls 26,28 are bolted or otherwise secured to the webs of vertical channel framemembers 48 which extend along the joints formed by the abutting oroverlapping edges of the panels I panels.

Horizontal braces 47 extend between adjacent channel frame members 48 alng the outer surfaces of panels 36 or 36' to strengthen the middlepanels 36 or :36 of the side and end walls. Braces 47 are not'providedfor the comer panels of the side and end walls where the additionalbracing is not needed. As shown in FIG. 4, which has some of the braces47 removed to better illustrate the construction, and FIG. 5, the websof horizontal braces 47 extend beyond the flanges at each end of thebrace to, form tongues which are received in slots 49 of channel framemembers 48. During assembly of the pool, one of the tongues is insertedin a slot 49 of a frame member 48 already secured to panels 36 or 36'and the other end is inserted in the slot of an adjacent frame member 48prior-to securing the frame member 48 to the wall panels. 5 Poolsidewalls 22 and 24 extend perpendicular to pool end walls 26 and 28with the tank of the pool thereby being rectana girlar in horizontalcross section. The rectangular configurationof the pool with theresulting right angle corner joints,

FIG. 9,'enables the pool corners to' be constructed soas to provide formaximum strength. The comer panels at each of the comer joints arebolted to vertical angle or W shaped support frame members 50 or similarangle members which lend great strength and rigidity to the poolstructure. While this construction is very strong and durable, it is notdesirable to have a pool with right angle comers since the water withinthe pool tends to stagnate in such comers resulting in an accumulationof dirt. To eliminate stagnant water and dirt accumulation in the sharpcomers and to reduce burbling of the water circulation, therebyimproving filtration, corner cove panels 52 are provided at each comerof the pool. The corner cove panels 52 extend from channel or L shapedextensions 40, 40' which are mitered at the comers to insure a properfit, to the upper edges of the wall panels 36, 36'. The inner surfacesof panels 52 are generally smooth and concave thereby rounding out thecomers of the pool so that there are no places for the water within thepool to stagnate. These panels 52 are bolted or'otherwise secured tocomer panels 36, 36' and as can be readily appreciated, not only improvethe circulation of water within the pool, but also provide anaesthetically pleasing appearance. j v

The sidewalls 22 and 24 of the pool are provided with external torsioncables 54, 56, respectively, which hold the deck from extensions to theupper edges of the panels or sections in and down. As best shown inFIGS. 4, 7 and 8, the cables are secured at each end of the verticalcorner support frame members 50 at points spaced below the upper edgesof the pool walls by means of brackets 58, 58', which are bolted, weldedor otherwise secured to the corner frame members. The brackets 58, 58'are made up of legs 60,60 and 62, 62', which extend perpen-dicular withrespect to each other, and diagonal extensions 64, 64' that divergeoutwardly from the pool sidewall and which are integral with legs 62,62'. The cables 54 and 56 are mounted on the brackets by means ofcableclevis or yokes '66 having pins which pass through apertures inthediagonal extensions 64, 64' of the brackets. Turn buckles 67 and 67' areprovided in each cable so that the tension in the cable can beadjustedas necessitated.

Center deck and cable support struts 68 and 70 are positioned midwayalong the upper edges of sidewalls 22 and 24, respectively, and extendperpendicular to the sidewalls 22, 24 in a generally horizontal plane.The struts are bolted to the undersides adjacent deck panel sectionswith the struts extending along the joints formed by the middle deckpanel sections of sides 22, 24. The inner ends of struts 68 and 70 donot abut frame members 48 and the outer ends are engaged by the torsioncables 54 and 56. In the preferred form of the invention, a horizontallyextending notch 71 is provided in the outer edge of each center deck andcable support strut within which is mounted tube 72 or some similarelement which preventsthe torsion cable from chafing.

As can be readily seen from FIGS. 4 and 7, the center deck and cablesupport struts 68 and 70 are mounted on thefundersides of abutting deckpanels of the swimming pool at a greater height than the ends of thetorsion cables '54 and 56 which are secured to the brackets at thecomers of the pool. As a result of this assembly, the lines of forceacting on the center deck and cable support struts 68 and 70 not.onlyare directed inwardly, but alsodownwardly so that the cables help tohold deck34inanddown. I

FIGS. 17 and 18 are diagrammatic views illustrating modifications of thetorsion'cable assembly to be utilized on pools of greater width andlength than the one illustrated in FIGS. 1 to 4. FIG. 17 illustrates apool which is of such a width that torsion cable assemblies 200, 200,similarto those illustrated in FIGS. 7 and 8, are required along theends of the pool as well as the sides. The brackets 202, struts 204 andcables 206 utilized in the assembly of FIG. 17 can be the same as thoseof FIGS. 7 and 8 or, if desired, along the end of the pool having thewide deck, the cables can' be secured to the cable support struts atpoints spaced inwardly from the outer end of the struts. FIG. 18illustrates a second modification of the torsion cable assembly for useon a pool of greater width andlength than the pool illustrated in FIGS.1 to 4; The torsion cable assemblies along the ends of the pool are thesame as those illustrated in FIG. 17-.'I-Iowever, due to the length ofthe pool, torsion cable assemblies 208, 210 and 2l2 are not only securedon each side of the pool to the center deck and cable support strut 214,but also deck and cable support struts 216, 218 on either side of thecenter deck and cable support strut. Support struts 216, 218 are securedto deck at the joints between the middle panel sections 220, 222 andpanel sections 224, 226 respectively, while strut 214 is secured to thedeck at the joint between the middle panel sections in the same mannerthat struts 68 and are joined to the deck 34. With the abovearrangement, the outer edges of a pool deck of great length and widthcan be securely held down and in place.

The floor of the pool can be flat, level or concave as shown by floor 30in FIG. 4, or, as shown in FIGS. 1 to 3, the pool can be provided with ahopper at one end which extends below the surface of the ground. When itis desired to have a pool with a flat, level or concave floor such as30, a' flexible liner 73 of water-proof material is laid over sand orsuitable fill enclosed by the sidewalls and end walls of the pool andthe liner is secured to hangers on deck 34 and adjacent the upper edgesof sidewalls 22, 24 and end walls 26, 28 as will be fully explainedhereinafter. Of course, a suitable drain can be pro vided in the floorof the pool which, in combination with outlet 74 in end wall 26,connects the tank of the pool with the conventional pump and filtrationsystem 75. I

When it is desired to construct a pool with a hopper, a tubular frameassembly 32, such as the one shown in FIGS. 2and 3, is utilized. Frameassembly 32 is laid within an excavation at one end of the pool and ismade up of a lower square center framework 76, a larger upper squareframework78 and connecting members 80 which extend from the comers offramework 76 upwardly and outwardly to the comers of framework 78. Thetubular frame members of the assembly are bolted, welded or otherwisesecured to each other along their abutting edges. As in the embodimentutilizing a flat, level or concave floor, the interior of the pool islined with a flexible liner 73 of water-proof material. The liner islaid over sand or other suitable fill at the shallow end of the pool andover the tubular frame assembly 32 at the deep end of the pool with theliner being so shaped as to conform to the contours of the tubular frameassembly 32. As in the previous embodiment, a drain 81 can be providedin the liner which is mounted on strap 82 extending between tubularframe members of lower framework 76.

As best shown in FIGS. 6 and 14, the peripheral edges of liner 73 isheat sealed or otherwise secured to vertical extensions 83 of extrudedvinyl hooks 84. Hooks 84 are retained on hangers 85 which extend aroundthe inner edge of deck 34.

Hangers 85 are preferably made of extruded aluminum members and comprisebase portions 86 that are secured to deck 34 by bolts which pass throughdeck panels 94 and into nuts mounted in upper flanges 100 of thevertical wall panels 36 or 36'. Hanger members 85 have vertical webportions 87 extending upwardly from the inner ends of base portions 86and horizontal flanges 88 which extend outwardly from the upper end ofweb 87 to form hooks which retain hooks 84 of liner 73.

An extruded vinyl coping 89 is provided to cover the hanger assembly andhelp retain the complementary hooks of the hanger assembly (members 84,85) in place. Coping 89 has a hollow section 90 with a convex innersurface that extends below extensions 83 to cover the upper edges of theliner 73 and give the inner rim of the pool an aesthetically pleasingappearance. Hook portion 91 extends outwardly from the upper end ofhollow section 90 and when the coping 89 is in place, FIG. 14, hookportion 91 overlies hook 84 and is retained on hangers 85. A resilientextension 92, which, as shown in FIG. 15, is normally curved, mergeswith hook portion 91. Extension 92 covers the outer ends of hangers 85and due to its resilience, maintains hook portion 91 on hanger 85thereby insuring that the coping 89 is firmly anchored in place.

The elevated deck 34, which extends around the upper edge of theswimming pool tank, is approximately 2 feet wide along sidewalls 22, 24and end wall 28 and 6 feet wide along end wall 26. As shown in FIGS. 6and 10, the deck comprises a series of plywood panels 94 which havecomplementary alignment dowels 96 and apertures 98 along their abuttingedges; while the outer edges of the panels have molding strips 99secured thereto which hide horizontal deck frame members 102 andstrengthen the outer perimeter of the deck. The inner edges of panels 94extend along and are supported by the upper flanges 100 of the verticalwall panels 36. The bottom surfaces of panels 94, adjacent theirabutting edges, have wood nuts 104 mounted therein that are aligned withapertures in the horizontal deck frame members 102 which extend part ofthe way along the joints of the deck panels 94 from the outer edge ofthe deck to points spaced from the side or end walls. Bolts passing upthrough the webs of the channelshaped horizontal deck frame membersrigidly secure the deck 34 to these members. In addition, a series ofholes are provided in panels 94, which are aligned with apertures in theupper wall flanges 100 of the vertical sidewall panels 36 so that theinner ends of the deck panels can be rigidly secured to the side and endwalls by the same bolts which secure hangers 85 to the deck. With theuse of coping 89 around the inner perimeter of the deck along with woodnuts 104, the deck has a smooth upper surface completely free ofobstructions.

The outer edge of deck 34 along sidewalls 22,24 and end wall 28 issupported by diagonally extending frame members 106. Members 106 arebolted, pinned or otherwise secured at their lower ends to the verticalframe members 48 adjacent the lower ends of the vertical frame membersand have plates 108 welded to or fabricated as part of the-upper ends ofthe diagonal frame members 106. As best shown in FIG. 16, plates 108 aresecured to the outer edges of the deck panels 94 by jack assemblies 150.Jack assemblies 150 comprise studs 152, railing base members 154, plates108, nuts'l56, 158, 160 and plates 162 or extensions of the webs offrame members 68, 70 or 102 when the jack is located at a joint betweendeck panels 94. The heads of studs 152 are mounted within railing basemembers 154 and extend downwardly through apertures in panels 94, plates162 or the web extensions and plates 108. Nuts 156 are tightened againstplates 162 or the web extensions to rigidly secure the base members 154and plates 162 or web extensions as well as studs 152 to the deck. Nuts158 and 160 engage the upper and lower surfaces of plate 108 so that byloosening and tightening nuts 158, 160, the level of the outer edges ofdeck 34 along sides 22, 24 and end 28 can be adjusted.

Unlike the diagonal support-frame members 106 along sides 22, 24 and end28, no jack assemblies interconnect the upper ends of diagonal supportframe members 112 to the deck along end 26 of the pool. Instead plates114 of the diagonal frame members are rigidly secured to the deck in afixed position by studs passing down from railing base members 154.Diagonal support frame members 112, instead of extending from the lowerend of the vertical end wall frame members 48, extend upwardly from andare bolted to l-inch-diameter extension tubes 116 which are, in turn,secured at their inner ends to the lower portions of vertical wallsupport frame members 48. These extension tubes are, in turn, linkedtogether by a series of frame members 118 which run parallel to end wall26.

As shown in FIG. 1 1, the outer ends of extension tubes 1 16 areprovided with deck leveling jack assemblies 120 which each comprise astud 122 that is mounted on a plate 124 and passes through a pair ofapertures in one of the extension tubes 116. Nuts 126 are provided oneither side of the extension tube 1 16 so that by loosening andtightening the nuts 126, the level of the outer ends of extension tubes116 can be al-' tered, thereby altering the elevation of the outer edgeof the deck.

As-shown in FIGS. 11 and 12, the diagonal support frame members 108, 114are preferably made from either H shaped frame members or T shaped framemembers. These frame members 108, 114 not only support the elevateddeck, but also carry decorative panels 128 which extend from the lowerends of frame members 108, 114 to the upper ends of these members togive the outside of the pool an aesthetically pleasing appearance. Thesepanels 128, which are preferably either the coiled type, awning type ornarrow panel type, are made of plastic, aluminum, wood or similarmaterials and are slid into position between adjacent diagonal deckframe members.

When using the H shaped frame members, the decorative panels aremaintained in place between the 130, 130' on each side of the web sothat there is no need for using screws, bolts or other types offasteners to keep the panels in place. In the preferred form of theinvention, approximately 6 inches of the rear flange 130' of the Hmember is cut away at the top to permit the panels 128 to be slid intoplace. However, it is contemplated that the amount of flange 130' whichis cut away can be varied as required by the type of decorative panelused.

When a T shaped frame member is utilized, the lateral edges of the outersurfaces of the decorative panels 128 rest on flanges 132; while theinner surfaces of the decorative panels adjacent their lower andupperedges engage vertical sidewall frame members 48 and/or a stop means 133on extensions 116 pairs of flanges I and horizontally extending plates108 or 114, respectively, which thereby maintain the decorative panels128 in place.

Roll-away stairs 134 (FIG. 13) are mounted at one end of the pool toprovide access to and from the deck 34. The upper end of the stairs areprovided with a pair of outwardly extending roller 13b which arereceived in spaced-apart roller tracks 138 mounted on the underside ofthe deck and secured by bolts or similar means to the flanges of two ofthe horizontal deck support members 102. The spaced-apart pair of tracks138 extend parallel with regard to each other from the outer edge of thedeck to points adjacent the vertical end wall 26 and are provided withstops or protrusions 140 at the inner and outer ends to keep the rollers136 of ladder 134 from rolling otf the tracks. While in the preferredform, the tracks 138 are generally C shaped with each track having aslot extending longitudinally along one side through which the supportaxles for rollers 136 pass, it is contemplated that tracks 1 38 can beof any suitable cross-sectional configuration. With this arrangement,the stairs can be stored (as shown in dashed lines in FIG. 2) under deck34 simply by raising the lower end of the stairs and pushing thestairsinwardly until rollers 136 engage the inner stops 140. Apenures141 can be provided in one of the tracks so that a lock, similar to abicycle lock, can

be utilized to prevent the stairs from being pulled out of storage byunauthorized persons.

For the safety of those using pool 20, the pool has a railing 142 thatextends entirely around and is secured to the outer perimeter of deck34. The railing has a gate 144 directly above stairs 134 and, asdiscussed above, base members of the railing form an integral part ofthe deck leveling assemblies along sides 22, 24 and'end 28.
